A kind of printing ink washing agent and preparation method thereof
Technical field
The present invention relates to printing cleaning technique field, particularly a kind of printing ink washing agent and preparation method thereof.
Background technology
Printing equipment needs the dirts such as routine cleaning greasy dirt and ink marks in process of production.Change ink kind time or print job complete after need the ink on ink roller to clean up, and softening drum, silk screen, press plate and the type matrix on printing press can be infected with ink in printing process, also tackle printing machinery for keeping the standard state of printing press and the quality of printed matter and clean.
Existing detergent for ink is mainly divided into two large classes: a class is vapour, kerosene, and another kind of is print special novel printing ink cleaning agent.
Gasoline and kerosene are a kind of wide spectrum organism solvents, and proportion is little, and evaporation rate is fast, cheap.In existing printing house of China, major part also uses gasoline and kerosene to clean ink.As detergent for ink, there is a lot of shortcoming in gasoline and kerosene: one is safety problem, and vapour oil flash only has twenties degree, if the ventilation equipment in printing factory building is bad, is easy to the situation of causing danger; Two is pollution problems, and gasoline and kerosene, as a kind of organic solvent, have certain toxicity, if Long Term Contact, must cause destruction to a certain degree to the environment of the healthy of workman and surrounding.Novel printing ink cleaning agent is compared with kerosene with gasoline, and cleaning performance is good, and safety performance is high, and little to the pollution hazard of human body and environment.Novel printing ink cleaning agent is normally made up of solvent, tensio-active agent, auxiliary agent, water.Solvent conventional is at present still from non-renewable solvent oil, such as kerosene, and smell is large, and degradation property is poor, still there is certain threat to environment.
Summary of the invention
The object of this invention is to provide a kind of printing ink washing agent and preparation method thereof.
In order to realize object of the present invention, the present invention is by following scheme implementation:
A kind of printing ink washing agent, be made up of the raw material of following weight part: aviation kerosene 15-18, dibutyl phthalate 3-5, fatty alcohol-polyoxyethylene ether 5-7, Sodium dodecylbenzene sulfonate 2-3, thanomin 1-2, sodium carbonate 3-4, methyl oxirane 10-12, to the 3rd amyl phenol 2-3, sodium methyl cocoyl taurate 3-4, sodium xylene sulfonate 2-3, auxiliary agent 4-5, water 100-110;
Described auxiliary agent is made up of the raw material of following weight part: Silane coupling reagent KH-570 2-3, ricinolic acid 3-4, methacrylic acid-2-hydroxy methacrylate 2-3, neopentyl glycol 3-4, vinyl acetate 2-3, oxidation inhibitor 10352-3, ethanol 14-16; Preparation method is by Silane coupling reagent KH-570, ricinolic acid, ethanol mixing, is heated to 60-70 DEG C, stirs after 20-30 minute, then add other remaining component, be warming up to 80-85 DEG C, stir 30-40 minutes, to obtain final product.
Printing ink washing agent of the present invention, be made up of following concrete steps:
(1) at room temperature by aviation kerosene, thanomin, sodium carbonate, methyl oxirane, add in mixing kettle to the 3rd amyl phenol, add in mixing kettle after the water of half amount is heated to 65-75 DEG C, be stirred to and dissolve completely;
(2) dibutyl phthalate, fatty alcohol-polyoxyethylene ether, Sodium dodecylbenzene sulfonate, sodium methyl cocoyl taurate, sodium xylene sulfonate are added in mixing kettle, add surplus be heated to 80-90 DEG C water, with the speed of 1200-1300 rev/min stir 4-6 minute;
(3) finally auxiliary agent and all the other remaining components are added in mixing kettle, stir, naturally cooling.
Excellent effect of the present invention is: the present invention adds auxiliary agent, improves the processing performance of clean-out system, reduces its toxic side effect and the pollution to environment; The present invention fills a prescription simple, simple for production, stable performance, use safety, nonflammable, not etching apparatus, non-environmental-pollution, and cleaning performance is good, safety non-toxic, and raw material is simple and easy to get, easily stores, and stability is high, has wide market outlook.
Embodiment
Below by specific examples, the present invention is described in detail.
A kind of printing ink washing agent, is made up of the raw material of following weight part (kilogram): aviation kerosene 15, dibutyl phthalate 3, fatty alcohol-polyoxyethylene ether 5, Sodium dodecylbenzene sulfonate 2, thanomin 1, sodium carbonate 3, methyl oxirane 10, to the 3rd amyl phenol 2, sodium methyl cocoyl taurate 3, sodium xylene sulfonate 2, auxiliary agent 4, water 100;
Described auxiliary agent is made up of the raw material of following weight part (kilogram): Silane coupling reagent KH-570 2, ricinolic acid 3, methacrylic acid-2-hydroxy methacrylate 3, neopentyl glycol 3, vinyl acetate 2, oxidation inhibitor 10353, ethanol 14; Preparation method is by Silane coupling reagent KH-570, ricinolic acid, ethanol mixing, is heated to 60-70 DEG C, stirs after 20-30 minute, then add other remaining component, be warming up to 80-85 DEG C, stir 30-40 minutes, to obtain final product.
Printing ink washing agent of the present invention, be made up of following concrete steps:
(1) at room temperature by aviation kerosene, thanomin, sodium carbonate, methyl oxirane, add in mixing kettle to the 3rd amyl phenol, add in mixing kettle after the water of half amount is heated to 65-75 DEG C, be stirred to and dissolve completely;
(2) dibutyl phthalate, fatty alcohol-polyoxyethylene ether, Sodium dodecylbenzene sulfonate, sodium methyl cocoyl taurate, sodium xylene sulfonate are added in mixing kettle, add surplus be heated to 80-90 DEG C water, with the speed of 1200-1300 rev/min stir 4-6 minute;
(3) finally auxiliary agent and all the other remaining components are added in mixing kettle, stir, naturally cooling.
Be applied to by ink on the stainless steel metal thin slice of certain mass, dry under state of nature, steel disc is placed in the beaker filling clean-out system, soak after 5 minutes at 25 DEG C, more at the uniform velocity vibrate 5 minutes, obtaining clean dirt rate is 91.9%, and cleansing power is good.With this clean-out system with compared with gasoline, kerosene, rubber cloth increases the service life 2 years, and ink roller can increase the service life 3 years.
